Overview | monopentaerythritol, dipentaerythritol and tripentaerythritol (referred to as single-season, double-season and triple-season) are fine chemical intermediates, in the high-grade lubricating oil, polyurethane, PVC heat stabilizer, plasticizer, fire retardant and coating, ink and other aspects of a wide range of applications, especially in the double season, three seasons in high-grade aviation lubricating oil, photosensitive coating and ink and other aspects of pentaerythritol incomparable superiority. At present, there are few manufacturers in the world in the two seasons and three seasons, and the output is low. The domestic and foreign markets in the two and three seasons have been in short supply, and the price ratio of single, double and three seasons has been maintained at 1: 4.5: 3.5 for many years. |
Application | , advanced Lubricants, adhesive coatings, textile softeners, refrigerants and dispersants and other fields.|
preparation | a method for the preparation of Tri-pentanol, including condensation, distillation dealdehyde, evaporation crystallization, centrifugation, and, the basic steps of drying and the like are characterized by further comprising the following steps: first, preparing 31% formaldehyde, 50.4 acetaldehyde, 5.25m3 acetaldehyde, and 98% liquid alkali, 9.45m3, respectively, in a high-level tank, then, the concentration of 31% formaldehyde is put into the condensation tubular reactor at a rate of 16.8/h. After 2 minutes of formaldehyde feeding, the liquid alkali is put into the condensation tubular reactor at a rate of 3.15/h, finally, 2 minutes after the feeding of liquid alkali, acetaldehyde is put into the condensation tubular reactor at a rate of 1.75/h. When the temperature of the tubular reactor reaches 45 ℃, the cooling water is turned on to control the heating rate, the heating rate is 1 ℃/5min, until all the feeding is completed, transfer the reaction solution to three condensation vessels, stir until the reaction is complete, and keep the heat for 10 minutes, the pH value of the neutralization solution with formic acid concentration of 85% is 6~6.5, when the temperature is 60 degrees C, the condensation liquid containing three Quaternary pentanol is sent to the sedimentation tank, Open the stirring, and, the stirring speed is 15r/min, and the temperature is cooled to 25 ° C by circulating water for 2 hours, and the temperature is cooled at 2 ° C/h. After the condensation liquid after the heat preservation is settled for 24 hours, Filtration was carried out in a filter press so that the moisture content in the filter cake was less than 20%. The filtered cake is pressed to obtain 200 of wet material, which is sent to the rotary kiln dryer for the first drying to a moisture content of 5%, it was further dried in a rotary dryer until the moisture content of the filter cake was less than 1% to give 140 of the finished tripentanol. |
